👜 What is a CTP Bag?
- A standardized test bag containing specific objects, shapes, and materials (such as wires, sheets, organic/inorganic blocks, and sometimes dummy explosives).
- It is defined by international standards like ECAC (European Civil Aviation Conference) or TSA (Transportation Security Administration).
- Designed to simulate threat scenarios in a repeatable, controlled way.
🎯 Purpose / Uses of a CTP Bag in XBIS
- Performance Testing
- Ensures the X-ray machine can detect explosives, weapons, or prohibited items as required by regulators.
- Confirms both image quality and automatic detection algorithms are working.
- Calibration & Validation
- Used after maintenance or software updates to check that the XBIS still meets detection standards.
- Ensures consistency of detection sensitivity across different checkpoints.
- Operator Training & Testing
- Helps train screeners by presenting “hidden threats” in a standard way.
- Used for competency checks to ensure operators can correctly identify threat items.
- Regulatory Compliance
- Authorities (ECAC, AERB, TSA, etc.) require XBIS to be regularly tested with CTP bags.
- Forms part of certification and quality control in aviation and critical infrastructure security.
🛠 Example
A typical ECAC CTP bag may contain:
- Wires & detonator-like objects (to test cluttered detection).
- Organic simulants (to test explosive detection).
- Metal plates or rods (to test density penetration).
- Guns or knife replicas (to test prohibited items recognition).
If the XBIS correctly highlights/alarms for these items, it passes the performance check.
